Which algrithm is used for dominator tree calculation? [message #1117321]

Hi!

For my studies I'm writing a paper about heap dump analysis tools.
In the case of the memory analyzer I wonder what algorithm is used for dominator tree calculation?

I looked in the code but couldn't identify the algorithm without having to thoroughly analyze it.
I think the 2 most "popular" algorithms are from Lengauer (1979) [1] and Cooper (2001)[2].

Does anyone which algorithm in particular is used by the MAT?

Hi,

In MAT we followed the Lengauer & Tarjan algorithm. I guess it could be difficult to recognize it because of our internal structures how objects and their references are represented Smile
